IMPROVEMENT IN CARBURETERS.

Specification forming part of Letters Patent No. 59,446, dated November6, 1866.

To all whom it may concern:

Be it known that I, FRANCIS S. PEAsE, of Buffalo, in the county of Erieand State of New York, have invented a new and useful Improvement inOarbureters; and I do hereby declare the following to be a full, clear,and exact description of the same, suflicient to enable one skilled inthe art to which the invention appertains to make use of it, referencebeing bad to the accompanying drawings, which form a part of thisspecification, and in WhlOl1 Figure 1 is a vertical central section.Fig. 2 is a vertical central section of a modified form of air-pump.Fig. 3 is a vertical central section of a modified form of deflector inthe carbureting-chamber.

This improvement is adapted for positions and conditions where it is notconvenient to obtain a blast of air through the carbureter, by theconstant movement of machinery; and it consists inthe provision, inconnection with a carbnreting-chamber and hydrocarbon reservoir, of astrong chamber, to be filled with compressed air, and the air-pump maybe a permanent fixture upon it, or the air is forced into the cylinderby stationary machinery. It is particularly adapted for locomotiveheadlight, railroad and street cars, and coaches, dwellings, andlight-houses.

In the drawings, A is an air-pump for the condensation of air into thechamber B. It passes thence by the pipe 0 to the rose D in thecarbureting-chamber E, ascending into the deflector F, which is aninverted vessel with notches on its lower edge. As the entering airfills the deflector it issues from thence at the orifices made by theserrations in the edge thereof, and ascends through the perforated orreticulated plate G, which serves to mix the passing air and gas, andrender it more homogeneous in quality. The diaphragm G also prevents theswashing of the liquid when the carbureter is placed upon a body inmotion, as upon a locomotive, or street-car, &c. The gas passes from thegenerator, by the pipe H,

to the burner, which is represented in Fig. 1 as ahead-light with areflector. The hydrocarbon fluid, which may be gasoline or anysufliciently light and vaporizable hydrocarbon, is supplied to thegenerator by the pipe I from the reservoir J, which is filled by theopening K.

The carbureting-chambers shown in Figs. 1 and 3 are substantiallysimilar, the difference being mainly in the form of the deflector. Ineach case the bottom of the chamber is dishing, With'the rose in thecenter.

The air-pump shown in Fig. 1 is the ordinary single-acting pump, with avalve in the plunger, and one in the bottom of the cylinder, eachopening downward, and the communication with the compressed-airreservoir is maintained or intercepted by the stop-cock L.

In Fig. 2 a modified form of air-pump is shown, in which water is usedas a packing above the diaphragm M, the piston elevating a body of airat each upward stroke, which passes through the small openings in thediaphragm M, and up through the Water lying thereon, the valves closingupon the diaphragm when the pressure below is removed. By this means theair is prevented from returning, as the water forms a joint upon thevalves on the diaphragm, and the parts are not obliged to be air-tight.The piston-head may be covered similarly with a small quantity of water.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

The combination, with a carburetingchamber, of a strong reservoir, forcontaining a supply of compressed air, substantially as and for thepurpose described.

2. The mode of operating the air-pump with a waterpacking above thevalve or valves, substantially as described.
